mining method selection

Shaft: Site Selection, Shape, Depth & Pillar
Considerating D depth of shaft in m, t = thickness of the seam in m, R – radius of shaft pillar in m. 1. DRON'S Rule – Area of the shaft pillar = area to be supported + D/6 on all sides. 2. Foster's rule – R = 3√Dt. 3. Wadin's Rule – For shafts upto 100 m depth, size should not be less than 36.5 x Get Price
